The Royal Canadian Mounted Police arrested the woman at Halifax Stanfield International Airport and took her to the hospital to be evaluated.
The 37-year-old woman wanted to keep the plane from taking off because she thought that her husband was leaving to see another woman.
"Her intent was to stop the aircraft from taking off," RCMP spokesman Sgt. Al LeBlanc told Q13 FOX. "She jumped the security fence, but she was nowhere near the aircrafts. The airport staff and the Mounted Police responded right away and apprehended her."
Even though the woman's attempt was unsuccessful, security staffers are still nervous about how close she came.
"We don't believe that there are (any gaps)," airport authority spokesman Peter Spurway told the Chronicle Herald. "But the details of how she got over that fence will be reviewed just to see if there's anything else we would need to do in that area to ensure the airfield is as secure as we can make it."
The woman will likely not face charges from the RCMP.
"We contacted her partner who indicated that he was not on the aircraft," LeBlanc said.
